Title: Gravitational waves from a particle physics perspective

Abstract:Continuing the success of gravitational wave observations requires
a large effort on improving their theoretical predictions in the next
decade, in order to keep their accuracy on par with improvements of the
detectors. This requires innovations on the methods by which
gravitational waves from compact binaries are calculated. In this talk,
we focus on approaches to analytic, perturbative predictions for
relativistic binaries inspired by high-energy physics. In this area,
effective field theories are highly useful and scattering amplitudes
(the primary observable) can be calculated very efficiently using
novel tools. These methods can indeed be applied the classical binaries
and their gravitational waves. We give a basic introduction to the
ideas of these approaches and recent progress.
